It's not even so much honesty exactly...how do I describe it...it's just a straight-forwardness that older people seem to prefer because they've been there and done that with the games and beating-around-the-bush that characterize younger dating and relationships.
Like, based on my own experience, with an older person you can fuck on the first date and there's no "did I give it up too quick?" emotional bull, because they've already been through that. They don't give a shit about "sexual purity."
Dating an older person, you can totally be like, "I've got finals. I'll call you sometime next week." And that shit is FINE.
Just...let it be what it is. That's the only way I can describe it; probably not too helpful. lol
